Speed issue with Frogatto and MiniGL 2.20

Since the installation of the new MiniGL 2.20 (Sam440 + Radeon 9250) i got various slowdown when i play with Frogatto (expecially in the external area of the game).. before, using the old MiniGL 2.5 there were some sporadic graphics problems in game (in a couple of areas i had a white screen instead) but in general the game was always pretty fast and smooth even at the most higher resolutions

However while (thanks to MiniGL 2.20) the graphics are perfect everywhere now, game become a lot slower :-/ ... so slow that it become a bit unplayable on little machines like my Sam440 ! ...

I hope you can speed up the game a bit more in order to make it smoth again (even when using the latest version of MiniGL 2.20)

Indeed you are right, with the new MiniGL 2.20 Hans fixed various rendering issue that was affected various games, including Frogatto, however while now graphics are always correctly rendered (in all levels) the side effect of that improvements was a visible slowdown in game :-)

To gain some speed in Frogatto Hans suggested this changes:
 
"Frogatto could probably be sped up by modifying it to use GL_SMOOTH instead of GL_FLAT shading. Flat shading is slow with Warp3D because triangles have to be sent one at a time. W3D_SI users will probably notice less of a slowdown, because the driver does a reasonable job of working around this."
